the obama administration did not really secure a status of forces agreement that was going to protect american troops. they all pulled out. what's the situation in iraq right now? >> reporter: well, obviously the administration had hoped originally for some kind of a residual force in iraq to continue our mission there but wasn't really able to negotiate that with the iraqi government. one of the issues it tripped over was this immunity question. this is, typically comes up in these types of situations and of course it is a question of sovereignty from afghanistan and protecting the troops in our eyes. i expect this will be difficult with afghanistan as well. jon: the president has reportedly considered plans to leave maybe 3000, maybe 9,000 troops in afghanistan but there are commanders in the field said you need a lot more than that. where, if they come up with say, even that lower number, 3000, is that enough to get any kind of a job done? >> it seems unlikely, jon. unwith of the goals from the decade-long effort to stop terrorists from establishing a foothold in afghanistan again.
